Reach Stacker Tire System: Specifications and Selection Guide

Product Specifications

Technical details and manufacturing context for Tire System

Definition

The tire system on a reach stacker consists of specialized tires, wheels, and mounting components designed to support heavy container loads, provide stability during lifting operations, and enable precise maneuvering in port environments. It must withstand extreme weights while maintaining flexibility for tight turning radii. The system includes pneumatic tires with a standard size of 18.00-25, mounted on rims sized 13.00-25, and is rated for a ply rating of 28-36 PR. Each tire can support a load capacity of 15,000 to 25,000 kg, depending on ply rating and speed, and operates at a pressure of 1.0 to 1.6 MPa. The maximum speed for loaded operation is 25 to 40 km/h, and the tread depth for new tires ranges from 25 to 35 mm. The tire weight is between 180 and 250 kg, affecting total machine weight. The operating temperature range is -20 to 70 °C. The tread pattern is L4, suitable for severe rock service. Materials include rubber compound, steel belts, and nylon cord. These specifications are reference values per ISO 4251-1, and ISO 10261, and must be verified with the legal manufacturer or supplier for the specific model and application. The tire system's design ensures stability during lifting and maneuvering in port environments, but actual performance depends on proper maintenance and adherence to specified parameters.

Working Principle

The tire system transfers the vehicle's weight and operational loads to the ground through pneumatic pressure and rubber deformation, creating friction for movement and stability. The tires' construction and tread pattern are optimized for heavy loads, wet conditions, and frequent directional changes. The pneumatic pressure inside the tire supports the load, while the rubber compound and steel belts provide strength and flexibility. The tread pattern, L4, is designed for severe rock service, offering traction and resistance to cuts. The system's ability to deform and conform to surfaces allows for smooth operation over uneven terrain, while the rim and mounting components ensure secure attachment to the vehicle. Proper inflation and tread depth are critical for maintaining performance and safety.
